During 2018–2019, the U.S. Geological Survey (USGS) in cooperation with the Madison County Planning Department and the New York State Canal Corporation conducted a study of the Old Erie Canal between the Town of DeWitt, New York, and its junction with the current Erie Canal of the New York State Canal System near Rome, N.Y. The study comprised bathymetric, velocity, and water-quality surveys and documentation of the canal infrastructure. The USGS established benchmarks and staff gages along the 30.8 miles of the canal study area to reference the water-surface level in the canal to the North American Vertical Datum of 1988 (NAVD 88). Water-quality data (dissolved oxygen, water temperature, specific conductance, pH, and turbidity) were collected concurrently with the bathymetric survey (spring 2018) to characterize changes in water quality along the length of the canal. The canal infrastructure was documented to provide a baseline assessment. This dataset contains a shapefile representing water quality observations made with a multi-parameter sonde during the 2018 survey, and includes measurements of water temperature, turbidity, pH, dissolved oxygen, and specific conductance along parts of Old Erie Canal not navigable by boat. The purpose of this study was to document the current hydrology and hydraulics of a 30.8 mile long section of the Old Erie Canal and to provide data to water resource managers and land use planners to improve the water quality and aesthetics of the canal. 2022 Publication date Complete None -75.6777348 -75.5816181 43.2059466 43.1197666 USGS Thesaurus geospatial datasets water quality hydrology surface water quality USGS Metadata Identifier USGS:5f04c5ef82ce21d4c3f89c99 None Old Erie Canal United States New York State Madison County Oneida County Onondaga County None These points are defined for scientific research purposes and should not be used as a sole source of reference for any regulations and policy making.

PNG Environment as of Metadata Creation: Microsoft 10 Version 6.2 (Build 9200); Esri ArcGIS 10.7.1 (Build 11595) Service Pack N/A (Build N/A) All water quality sensors were calibrated prior to the survey following USGS techniques and methods (Wagner and others, 2006; USGS National Field Manual). Reference: Wagner, R.J., Boulger, R.W., Jr., Oblinger, C.J., and Smith, B.A., 2006, Guidelines and standard procedures for continuous water-quality monitors – Station operation, record computation, and data reporting: U.S. Geological Survey Techniques and Methods, book 1, chap. D3, 96 p. Ranges of water quality parameter measurements are consistent with historical values from Old Erie Canal for the time frame, and fall within the range of expected values. In the portions of the canal north of Durhamville where dense aquatic vegetation interfered with the echo-sounder transmission and numerous downed trees limited access by boat, water quality parameters were manually measured (surveyor waded into the canal) approximately every 0.19 miles along the centerline of the canal, concurrent with manually collected water depth observations. Horizontal positions of water quality observation points inherit their accuracy from Manual_Bathymetry_Points.shp. No independent testing was conducted to confirm the stated horizontal accuracy of the survey, but for the purposes of this study, the exact location of a given surveyed point in space was deemed to be less important than the relative locations among the surveyed points and the distances between adjacent points. All bathymetric data were referenced to the horizontal datum, North American Datum of 1983 (NAD 83). This processing step describes the collection of water quality data during the bathymetry survey conducted by John Wernly. In the portions of the canal not navigable by boat, water-quality data were collected manually using a Yellow Springs Instruments (YSI) 6920-V2 multiparameter water-quality monitor (Yellow Springs Instruments, 2012) at a depth of about 1.0 ft below the water surface. The multiparameter water-quality monitor measured dissolved oxygen, water temperature, specific conductance, pH, and turbidity at point concurrently with depth measurements. The synchronized times for individual water-quality measurements were coupled with the manually collected positional coordinates from the bathymetry survey to create a combined dataset as described by Foster and others (2016). 2020 U.S. Geological Survey, Northeast Region John F Wernly Hydrologist mailing address

Cortland NY 13045 US (607) 227-4145 jwernly@usgs.gov A shapefile containing point locations of water quality observations collected manually was created. This process step was performed John Wernly. a) Data from the multi-parameter water-quality monitor was imported into Microsoft Excel and plotted with time versus measured values to review the data for potential errors. Clearly erroneous data were removed from the dataset based on criteria set forth in Wagner and others. The table was exported as WQ_manual.xlsx. b) A shapefile was created in ArcMap v.10.7 from WQ_manual.xlsx using the "XY Layer Event" tool. c) The resulting shapefile was projected to WGS 1984 Web Mercator Auxiliary Sphere using the "Project" tool to obtain Water_Quality_Manual.shp. 2020 Vector Point 43 WGS 1984 Web Mercator Auxiliary Sphere (Esri Full Name: WGS_1984_Web_Mercator_Auxiliary_Sphere) 0.0 0.0 0.0 0.0 coordinate pair 0.6096 0.6096 Meter D_WGS_1984 WGS_1984 6378137.0 298.257223563 Water_Quality_Manual Table containing attribute information associated with the dataset.
